My invention relates to an article of furniture, and more particularlyto a reclining article of furniture, wherein the back-rest and seat formmovable members of a polygonal link-system swingably mounted on asupport, and wherein the movements of the members of said polygonallink-system are positively controlled by a guiding link pivoted to thesupport and operatively connected with a member of the polygonallinksystem.

An object of my invention is to provide a convenient controllingmechanism for a leg-rest swingably mounted on the seat of a recliningarticle of furniture of above described type, by means of which theangle between the leg-rest and the seat is automatically altered whenthe movable members of the reclining article of furniture including theback-rest and the seat are brought from a certain position, such as thesitting position, into another position, such as a reclined position, orvice versa.

Another object of my invention is to improve on reclining articles offurniture of above described type as now ordinarily made.

With the above and other objects of the invention in view, the inventionconsists in the novel construction, arrangement and combination ofvarious devices, elements and parts, as set forth in the claims hereof,certain embodiments of the same being described in the specification andbeing illustrated in the accom anying drawings forming part of thisspecification, wherein:

Referring now to Figs. 1 and 3, 29 generally indicates a support in theshape of a casing of any suitable material, such as metal, wood,plastic, or glass. A laterally projecting arm 22 is arranged on eachside of the chair at i s rear end. Each arm 22 is provided with a bore24. Furthermore, the support 29 carries a transverse rod 26, the ends ofwhich project on both sides of the support. 1

28 indicates a seat pivotally connected with a back-rest 30 by means ofpivots 32. On each side of he chair, one end of a connecting link 34hereinafter called the top connecting linkis pivoted to an intermediatepoint of the back-rest at 35. The top connecting links 34 form thearm-rests of the chair. The other end of each top connec ing link 34 ispivoted to one end of a second connecting link 35 hereinafter called thefront connecting link at 38. The lower end of said front connecting link36 is pivoted to the seat 28 at M. Thus. the pivotally interconnectedback-rest 36, the link-chain composedof, he two connecting links 34, andthe seat 28 form the movable members of a polygonal link-system in thesha e of a quadrilateral link-system. Said quadrilateral link-system is-swingably mounted on the support 2?.) at the pivotal connecion 32between the back-rest and the seat for movement abo t a single axis: oneach si e of the chair. the pivot 2 connectin the seat 2 3 with theback-rest 35 is inserted into the bore 24 of an arm '2 of the support2%. On each side of the chair, the movements of he movable members ofsaid quadrilateral link-system are controlled by a guiding link 42,thelower end of which is swingably mounted on the transverse rod 25carried by the support, and the upper portion of which is pivoted to thelink-chain or pair of connecting links 34, 36, at the pivotal connection38 between said connecting links.

A leg-rest 44 is pivoted to the front portion of the seat 28 at 46. Saidleg-rest 44 has an extension 48 on each side of the chair, saidextension projecting upwardly beyond the pivotal connection 46 betweenthe leg-rest and the seat. The extension 48 is rigidly connected withthe leg-rest 44. According to the invention, the movements of saidleg-rest 44 are controlled by a controlling link 50 arranged on eachside of the chair. One end of said controlling link 58 is pivoted tosaid extension 48 of the leg-rest 44 at 52, and the other end of saidcontrolling link 50 is pivoted at 54 to an extension 56 rigidlyconnected wi h the main body of the guiding link 42. Said extension 56of the guiding link projects outside the quadrilateral link-system.

The sitting position of the movable members of the chair shown in fulllines is limited by the upper edge of the support, on which, the seat.comes to a rest.

When the occupant of the chair leans the weight of his body against theback-rest, he may readily swing the movable members of the chair into areclined position, for example into the extreme reclined position shownin dash and dot lines in Fig. 1. As mentioned above, during such amovement the guiding link 42 controls the movements of the members 28',36', 34, 36 of the quadrilateral link-system and the movements of theleg-rest 44 through the medium of its extension 56 and the controllinglink 58.

The extreme reclined position of the movable members of the chair islimited by a stop 58 mounted on the support, which forms an abutment forthe back-rest.

The movable members of the chair may be held in. any desired position bymeans of a locking device generally indicated by 60. As best shown inFigs. 1 and 2, said locking device 60. comprises a handle 62 screwed onthe threaded end of the pivot 35 between the back-rest 35 and. the opconnecting link or arm-rest 34. Said pivot 35 has a head 64 restingagainst a surface of the back-rest 30. A square portion 66 of the pivot35 is inserted into a corresponding square aperture of the back-rest 38,whereby the pivot 35 is prevented from rotation. When the user of thechair loosens the locking handle 62, the

surface of the hub 68 of said handle is disengaged from the surface ofthe top connecting link 34, so that the movable members of the chair maybe freely moved from one position into another one. When th lockinghandle 62 is ightened, the surfaceof the hub of the handle is pressedagainst the top connecting link 34, whereby the latter is pressedagainst the back-rest 38 engaged with the head 64 of the pivot 35, sothat the members of the chair are held in their position.

Of course. if desired, any other type of locking device may be used.

Fig. 4 illustrates a different embodiment of a support a, on which themovable elements of the chair shown in Fig. 1 may be mounted. Thesupport 28a shown in Fig. 4 is in the shape of a casing closed at allsides.

It is understood, that the supports of the type shown in Figs. 3 and 4may also be made of.

several parts connected with each other in any suitable manner.

In the embodiment of a chair shown in Fig. 5, the quadrilaterallink-system I28, I38, I34, I36 swingably mounted on the support I28 atI32 and its control by the guiding link I42 substantially corresponds tosimilar mechanisms of the chair shown in Fig. 1. Furthermore, again oneend of a controlling link I55 is pivoted at I52 to the extension I48 ofthe leg-rest I44 swingably mounted on the seat I28 at I45. However, theother end of said controlling link I50 is pivoted to the guiding linkI42 at the pivotal connection I38 of the latter with the pair ofconnecting links I34, I36.

The sitting position of the movable members of the chair shown in fulllines in Fig. 5 is limited by the upper edge of the support I28 on whichthe seat I28 comes to a rest. When the backrest. [3.8 is swung about itspivot I32, the movable members of the chair are brought into a reclinedposition, for example into the extreme reclined position shown in dashand dot lines in Fig. 5. During such a movement the guiding link I42controls the movements of the members of the quadrilaterallink-system'as. well as the movement of the leg-rest I44.- The extremereclined position is limited by a self-locking effect of the mechanismwhich is obtained as soon as the controlling link and the extension ofthe legrest come into alignment. with each other in the position I58,I48 as shown in dash and dot lines.

Th movable members of the chair may be held in any desired position bymeans of a locking device ISB of the type shown in Fig. 2.

According to Fig. 6., the quadrilateral linksystem formed by the.pivotally interconnected seat 228., back-rest 230, and link-chain comrising the top connecting link 234 and front connecting link 236 isswingably mounted on the support 228 at 232. On each side of the chair,the lower end of a guiding link 242 is pivoted to the support 228 at22.6, and the upper end of said guiding link is pivoted to the topconnecting link 234 at a point 239 spaced from the pivotal connection238 between the top connecting link and the front connecting link. Theextension v248 of the leg-rest 244 pivoted to. the seat 228 at 248 ispivotally connected at 252 with on end of a controlling link 258,-theother end of which is pivoted to an intermediate point of the guidinglink 242 at 255. As will bereadily understood, the guiding link 242.controls the movement of the members of the quadrilateral link-system228, 23.0, 234, 236 and the movement of the legrest 244. The guidinglink 242, the front connecting link 236, the extension 248 of thelegrest, and the controlling link 258 are provided with series of holes278, and the pivots 238, 239, 252, and 255 are disengageable so thatthey may be inserted into selected holes of said series of holes 218,whereby the effective length of the guiding link, front connecting linkand controlling link may be varied and adjusted.

The movable members of the chair may be held in any desired position bymeans of a locking device 260 of the type shown in Fig. 2.

According to the embodiment shown in Fig. '7, the support 320 comprisestwo side frames 32I connec ed with each other by transverse bars 323,326.

The rear end of the seat 328 is pivoted to the back-rest 330 at 332. Therear end of the top connecting link 334 is pivoted to an intermediatepoint of the, back-rest 338 at 335, and the other end of said topconnecting link 334 is pivoted at 34I to an intermediate connecting link312 representing a portion of a guiding link 342 pivoted to the supportat 326. The upper end of the front connecting link 336 is pivoted at 3437. 1y connected with the-main body of the guiding link 642. pivotedtosaid extension 656 oiitheguiding link at 654, the other end 01? said:controlling link is pivotedat 652 to the extension'fi' lt 'of thelegrest' 644 pivoted to the seat at64fi. Thus, said guiding link 642also controls the movements of the leg-rest (WI through themedium of itsextension 656 and the-controllinglink 650;

The stop 614 limits-the sitting positionand the step 558- lim-its theextreme reclined position of the movable members of; the chair.

The movable members may be held in any desiredposition by means of thelocking devic 660. i

While according to Fig, 1-0; the extension 656 of the guidinglink isrigidly connectedwith the main body of the guidinglink; 642-, one end ofthe extension 156 of the guiding link'l' 42- shown in Figs.- ll and 13is pivoted tpthe guiding link at H6: The other end of the extension [56is pivoted at 154 to one end of the controllin link 150-, the'other endof which is piYQt d at 152 to the extension M8 of the leg-rest 144swingably mounted onthe seat 128' at 146.; The lower end of the guidinglink T42 is pivoted at 126 to the p o o s wn). ndh upp r d said guiding"link M2 is pivoted at 1531 to the front connecting link 1'36 piyot'allyconnected with the seat I28 at M9; The seat 128 and the front connectinglink 7-36 may form members of any of the polygonal link-systemsdisclosed in Figs. 1 and 5-10. v

'Theextension 156 of the guiding link is provided with a longitudinalguiding slot- TIB: According to Figs. ll 13-, the guiding link 14-2 isprovided with a guiding slot 180 having a recess 182 in register withthe lower end of the slot 156' when the extension'lkifi of the guidinglink is in the position'shown in full lines inFig. 11. An adjustingscrew generally indicated by l -84 passes through both slots ll-8 and180; The head 186 of the screw'lt i rests against the surface of theguiding link M2, and a square portion i88- oi the screw in slidableengagement with the slot I80 prevents the screw from rotation when anadjusting knob 190 is screwed on the threaded end of the adjustingscrew. When the adjusting screw 184 is tightened, the extension 156, ofthe guiding link is held in a predetermined position relative to themain body of the guiding link T42. When the adjusting screw is loosened,the extension T56 may be freely moved relative to the main body of theguiding link- 54-2; about its pivot H6, and, during such a movement, theadjusting screw 78-4 slides along the slots H8 and F80. v

When the extension 156 of the guiding link is One end of a controllinglink- 6504s in alignment with the guiding link [42 in the position shownin full lines in Fig. ll, the extension abuts against a stop F92 securedto the guiding link M2 by suitable means; for example screws. Said stop192, may cause a simultaneous movement of the guiding link 'HiZand theextension 156 of the guiding link when the guiding link is swung aboutits pivot ('25 and the adjusting screw 184 is not tightened.Furthermore, the extension 156 and the guiding link M2 are locked in. ai nm nt w h. each th r. n e adjusting screw 184. is displaced into therecess T82 of the slot 180 and into the end of the, slot "8 re isteringwith said. ece s As will be readily understood from Fig. 11, theleg-rest, 144 may be brought into. a different position relative to theseat 128, for example the position 1-44 by swinging theextension 156about its pivot 1-16, for example into the position 156-", after aloosening of the adjusting screw 1-84. Now, when the adjusting screw istightened in the position 184, the extension of the guiding link and theguiding link are rigidly connected with each other, so that the leg-restis held in the position 144. Upon a movement of the guiding link 142about its pivot 726, for example by a corresponding movement of theback-rest forming a member of the polygonal link-system including theguiding link as described above, the leg-rest is swung about its pivot146 starting from the position 144", until the movable members of thechair are locked, when the controlling link [50 comes into alignmentwith the leg-rest 1-44, In such a self-locking position of the movablemembers of 5 the chair, the backrest and seat have not yetreached theirextreme reclined position. If it is desired to bring the back-rest andseat into their extreme reclined position, the adjusting screw P84 is'loosened, whereupon the extension I56 of the guiding link abuts againstthe stop 792' under the weight of the leg-rest and the load actingthereon. Now, the back-rest and seat may be brought into their extremereclined-position, and, at the same time, the leg-rest isbrought intoits normal extreme reclined position by the guiding link 1G2 acting withits stop 192 on the extension'lSG of the guiding link connected with theextension I48 of the leg-rest 144 through the controlling link 150.

According to Fig. 11, the extension 156 of the guiding link is pivotedto an intermediate point H6 oi the guiding link 142. If desired,however, said pivotal connection between the extension 156- and theguiding link M2 may also coincide with the pivotal connection of theguiding link with a connecting link of the polygonal linksystem.

According to the embodiment shown in Fig. 14, a controlling element 856is swingably mounted on the guiding link 842 at 816. Said swingablecontrolling element 856 does not project outside the polygonallink-system including, for example, the topconnecting link 83 1, thefront connecting link 836, and the seat 823, and, consequently, does notform an extension'of the guiding link 842. However, the functions ofsaid swingable controlling element 856 pivoted at 854 to one end of thecontrolling link 850, the other end of which is pivoted at 852 to theextension 848 of the leg-rest 844, are substantially the same as thefunctions of the swingable extension 1-56 of the guiding'link shown inFig. 11. The controlling mechanism shown in Fig. 14 is also equippedwith an adjusting screw 884 passing through the slot 818 of theswingable controlling elements 856 and the slot 880 oi the guiding link842. Furthermore, again an abutment 892 is secured to the guiding link842 for engagement with the controlling element 856.

I haveshown certain embodiments of polygonal link-systems controlled bya guiding link. According to the invention, the movements of theleg-rest are also controlled by said guiding link through the medium ofa controlling link. It is understood, that said controlling mechanism ofthe leg-rest may also be applied to chairs having'a polygonallink-system controlledby a guiding link wherein, however, said polygonallink-system is of a somewhat different construction.

I have described preferred embodiments of my to said intermediateconnecting link 312. The lower end of said front connecting link 336 ispivoted to the seat 328 at 340. Thus, th pivotally interconnected seat328, the back-rest 330, the link-chain composed of the top connectinglink 334, of the intermediate connecting link 312 and of the frontconnecting link 336 form a quinquelateral link-system, which isswingably mounted on the support 326 at 332 for movement about a singleaxis. Tht movements of said quinquelateral link-system ar controlled bysaid guiding link 342 pivoted to the support at 326 and including theintermediate connecting link 312 of the link-chain as mentioned above.It is to be understood, that, if desired, the guiding link andintermediate connecting link could be made of two separate elementswhich are rigidly connected with each other by suitable means, forexample screws.

The leg-rest 344 swingably mounted on the seat 328 at 346 has an upperextension 348 pivotally connected at 352 with one end of a controllinglink 350. The other end of said controlling link 3511 is pivoted to anintermediate point of the guiding link 342 at 355. When th movablemembers of the chair are moved from one position into another one, theguiding link 342 controls the movements of the members of thequinduelateral link-system 326, 330, 334, 312,

336, and the movements of the leg-rest 344. The

sitting position limited by a stop 314 arranged on the support 326 isshown in full lines, and the extreme reclined position limited by a stop358 mounted on the support 326 is shown in dash and dot lines.

The removable members of the chair may be held in any desired positionby means of a looking device 366 of the type shown in Fig. 2 or of anyother suitable construction.

The support 426 of the chair shown in Fig. 8 is made of an integralpiece of tubular material bent in a suitable manner. The pivotallyinterconnected seat 428, the back-rest 436, the linkchain composed ofthe top connecting link 434; the intermediate connecting link 412 andthe front connecting link 436 form a quinquelateral link-system, whichis swingably mounted on the support 426 at 432 and corresponds to thequinquelateral link-system of the chair shown in Fig. 7. Furthermore,again, the intermediate connecting link 412 represents a portion of aguiding link 422 pivoted to the support 426 at 426, which controls themovements of the quinquelateral link-system.

456 indicates an element, which may be considered an extension of theguiding link 442 projecting outside the quinquelateral link-system.According to Fig. 8 the extension 456 is inte ral with the guiding link442, a portion of which represents the intermediate connecting link 412,but of course the extension 456 and the guiding link 442 could be madeof separate pieces of material, rigidly connected with each other in anysuitable manner. One end of the controlling link 456 is pivoted to theextension 456 of the guiding link at 454, the other end of saidconnecting link 456 is pivoted at 452 to the extension 448 of theleg-rest 444 pivoted to the seat 428 at 446.

As will be readily understood, the guiding link 442 controls themovements of the quinquelateral link-system and of the leg-rest. Themovable members of the chair may be held in any desired position bymeans of the locking device 460, the sitting position is limited by thestop 414, and the extreme reclined position is limited by the stop 458,both stops being arranged on the support 420.

According to Fig. 9 the support 526 comprises two side frames 52lconnected with each other by cross bars 523. The rear end of the seat528 is pivoted to the support 520 at 53] and the lower end of theback-rest 530 is pivoted to said support at the point 533 spaced fromthe pivotal connection 53l between the seat and the support. The rearend of the top connecting link 534 is pivoted to an intermediate pointof the backrest 530 at 535. The other end of said top connecting link534 is pivoted at 543 to one end of an intermediate connecting link 512.The other end of said intermediate connecting link 512 is pivoted at 543to the upper end of the front connecting link 536, the lower end ofwhich is pivoted to the seat 528 at 546. Thus, the movable back-rest530, the movable link-chain composed of the three connecting links 534,512, 536, the movable seat 528 and the stationary portion of the support526 between the pivotal connections 53l and 533 of the seat 526 and theback-rest 530 with the support 526 form the members of a hexagonallink-system. The upper end of a guiding link 542 is rigidly connectedwith the intermediate connecting link 512, and the lower end of saidguiding link is pivoted to the support at 526.

The extension 548 of the leg-rest 544 pivoted to the seat 528 at 546 ispivotally connected with one end of the controlling link 550 at 552. Theother end of said controlling link 550 is pivotally connected to anintermediate point of the guiding link 542 at 555.

When the back-rest 530 is swung about its pivot 533, the movements ofthe movable members of the hexagonal link-system 528, 520, 530, 534,512, 536 and the movement of the leg-rest 544 are controlled by theguiding link 542 so that, for example, the movable members of the chairare brought from the sitting position limited by the stop 514 into theextreme reclined position limited by the stop 558.

The movable members of the chair may be held in any desired position bymeans of the locking device 560.

In the embodiment shown in Fig. 10 the support 620 comprises two sideframes 62l connected with each other by cross bars 623.

The rear end of the seat 628 is pivoted to the support at 63l. The lowerend of the back-rest 630 is pivoted to the support at the point 633 at aslight distance from the point 63 I The rear end of the top connectinglink 634 is pivoted to an intermediate point of the back-rest 636 at635. The other end of said top connecting link is pivoted at 638 to theupper end of the front connecting link 636. The lower end of said frontconnecting link is pivoted to the seat 628 at 646. Thus, the stationaryportion of the support 620 between the pivots 631, 633, the movablebackrest 630, the link-chain composed of the movable top connecting link634 and the movable front connecting link 636. and the movable seat 628form the members of a quinquelateral linksystem. The movements of themovable members of said quinquelateral link-system are controlled by aguiding link 642, the lower end of which is pivoted to the support at626 and the upper portion of which is pivoted to an intermediate pointof the front connecting link at 631.

The upper end of said guiding link 642 has an extension 656 projectingoutside the quinquelateral link-system. Said extension 656 isrigidinvention, but it is understood, that this disclosure is for thepurpose of illustration, that the invention may also be applied tovarious other types of articles of furniture such as garden chairs,chairs for use in railroad cars, chairs for use in airplanes, sofas,loungets, etc., and that various omissions and changes in shape,proportion and arrangement of parts, as well as the substitution ofequivalent elements for those, herein shown and described, may be madewithout departing from the spirit and scope of the invention as setforth in the appended claims.
